OptimizeInstructions: Check for possible added-constant overflows (#5227)
Fix a regression from #5025 : we subtract constants there, and we need to be aware
that such subtraction can change a constant from signed to unsigned if the comparison
is signed, as
0x80000000 - 1 = 0x7fffffff
0x8000000 is a negative number when seen as signed, but always positive after the
subtraction.
